摘　　要：随着居民对出行质量要求的提高和公交都市等公交优先战略的推进,针对需要不断改善乘客出行信息不对称情况的目的。文中提出了一种地铁车厢人数测定的数据检测装置设计方案。基于实现对地铁车厢人数实时测定的目的,通过实地调研与仿真建立了车厢与传感器单元的基本模型,在大量既有车厢人数数据基础上,利用机器学习确定了传感器的最优布置方案,提出了传感器四角布置模型。为了使模型具有实际意义,设计了能实现信息获取和信息传输的简易装置。With the improvement of residents'requirements for travel quality and the promotion of transit priority strategies such as transit metropolis,it is necessary to continuously improve the problem of passenger travel information asymmetry.This paper presents a design of data detection device for the number of people in subway trains.In order to develop the real⁃time measurement of the number of subway trains,the basic model of the car and sensor unit is established through field investigation and simulation.On the basis of a large amount of data of the number of existing cars,the optimal sensor layout scheme is determined by machine learning,and the four⁃corner sensor layout model is proposed.In order to make the model practical,a simple device is designed to achieve information acquisition and transmission.
